TAXIMETER.

Application filed July 15, 1922. Serial Np. 575,262,

I' 0 all whom t any concern Beit known that I, ABRAHAM VEIsiNGaR, a citizenof the United States, residing in Newark, county of Essex, State of New Jersey, have'invented certain new and useful Improvements in Taximcteis, of which the followingv4 is a specification'.

Mylinvention relates to improvements in taximetersvof the kindl novvv employed on tapricabs. and lilie vehicles.

`Theprimal-Iyobject of my invention is to morefadvantageously position the mechanisms for recordingextras on a taximeter, and. to provide simple and positive means for manually operating said mechanisms to indicate, the desired charges.

Another obj ectv` of the invention is to operably connect therecording mechanism of the entras to the indicating flag in such manner` that when said flag is reset to Vacant `position the recording. mechanism off the extras will be resettoinitial position. `i i Other and-'further objects, ineluding;7 certain features of construction and application, will appear in` theispecification and be pointed out in the `appended claims, reference. being had to the accompanying drawings which show the preferred embodiment of my invention.

is a large square )late 8 which serves,l in conjunction with t e base plate as a` means for supporting several of the opera-tjrigi mechanisms. Located back of the plate S near the top of the instrument and fastened to the base plate by suitable postsV inV the same manner as plate 8, is a smaller late 9 adapted to act as a` supporti g member for some of the parts hereina ter explained. Fastened near the lower edge of the. plate. 8 and extending forwardly Vis al stud l0 upon which is mounted ar hub 11 said hubcarrying on its forward end a dial' 12A.` Radially disposed on the face of this dial adj cent the peripheral line, are numeralsw 2, Vo '18 with a blank space between.A 2 an 18whi1ch shows when the dialv is in. iiiitia` position'. Suitably fastened to the plate Sand extendingv forwardly and over the, dial 12 is screen 13.` having therein an openingflll; through which the numerals'on the dialA can be seen. Placed on this screen to the right of the opening 14 is a O the Vpiirpose "of which is to complete the sum of' the extra charges, that is so that they will' readu from 20.1; 0 180. By placing the' 0 on the screen I am enabled to enlarge the nnmeralson'the dial so that the extra charges canbe more readily observed. K

Forming part of the hub 11' is a, pinion 16 whichl meshes withk and is' drivenfby a vertical rack bar 17. The top of this rack bar meshes with and is driven by aT pinion 1,8. mounted on a shaft, 1,9 liournaled in the plates 8 and 9. The rack bar is hel'dginoperative position against the pinion by grooved guide plates 2O and`21 fastened respectively near the top. and bottom of plate 8, saidrack carrying thereon, near the top, a pin 17 adapted to engage the'top guide 2() and act as a stop to limit the.` upward*` movement of said rack.` Ilfivotally mounted on the plate 8 is a lever 23, oneend of which is slotted'` and hasriding freely in said slot a pin 24 carried, by rack bar 1,7, the other end of said Ieverhas apspring 25 fast nedthereto theopposing,endnofsaid spring eing fastened to a pin26 in Alate '8, The object o ithis, spring actuated everisk to draw the rack bar back to`its`initial position after the dialV l2. is released, as will hereinafter be more fully` explained, Mounted on one of the posts of the platre'ftl," is1 aL rock arm 27 the free end of which has Piretalllf- @Dewi/sd theme@ heriziiil af??? 28. To the underside of this arm 28 is pivoted a pawl 29 having, attached to the bottoni thereof a spring member 30 which pushes against a boss 8l on horizontal arm 29 thereby holding said paWl in the position shown in Figures 7 and 8. Freely mounted on a fixed stud 35 fastened in the plate 9 are two gear wheels 36 and 87, gear 3G meshing with and driving pinion 38 tired on shaft i9 and gear 37 operating the totalling mechanism, as hereinafter explained. Fas-.tened to the plate 9 is a stud 49 freely carrying thereon two dogs 4l and 42, dog 41 acting a detent on gear 36 and pawl 42 acting in a like manner on gear 37. Dog 42 is permanently held in engagement with gear 37 by a spring 44, said spring having one end fastened to the dog and the other end to a pin on the frame 9. In view of the fact that gear 37 always turns in the same direction it is not necessary to remove its dog for reset. A spring l5 also holds dog 41 in engagement with gear 36, While a pin 46 on the top of the dog engages the vertical arm of a bell crank lever 47 by which said dog is moved out of engagement with gear 36. The top arm of the bell crank lever engages a pin 49 in the free end of the horizont-.il arm 28 for the purpose of lifting said arm to free the pawl 29 from engagement with the gears 36 and 37. Carried by the rock arm 27 is a stud 50 which projects through a slot in the plate 9 and has mounted thereon between the plate 9 and the back plate 1, a roller 51, said roller being adapted to engage a cam 52 mounted on a shaft 53 journaled in the back plate 1. This shaft 53 has attached thereto outside the. back plate. a handle 54 for the purpose of turning said shaft and cam to operate the pawl 29. The cam 52 has two cut away portions 52 in one of which the cam roller 51 normally rests a tter pavvl 29 has progressed gears 36 and 87, and two high portions 52 which act to draw the pavvl back to position to permit said pawl to progress gears 36 and 37. A spring 56, one end of which is attached to the free end of horizontal arm 28 and the other end to the plate 9, tends to hold said arm, .rook arm 27 and pawl 29 in operative position, that is5 the position shown in Figure 7.

Pivotally supported on the 2l is a detent GO adapted to engage the pinion 16 and hold said pinion in the positions into which it is moved by the rack bar 17. This detent is normally held in engagement with the pinion by a spring 61, said spring being fastened to the detent and the plate 8.

Extending through and iournaled in the back plate 1 and the plate 8 is a shaft 65 carrying thereon outside the back plate the signal Hag 4, said dag having the same standard form and operation as those now guide plate in comm-on use on vehicles. r1`his shaft 65 carries thereon, between the back plate and 'the plate 8, a cam 68, Which once in every revolution of said shaft engages a cani roller 69 on the lower end of bell crank lever 47, and nic-ves said lever to the position shown in Figure 4, that is, so that the pavvl 29 Will be disengaged from the gears 36 and 37 and the dog 41 released from the gear 36. Also suitably fastened to this shaft 65, forward of the plate 8, is a cam 70 adapted to engage a cam roller 71 carried on the end of a vertically moving bar 72. This bar is held in desired position by pins 73 fastened in the plate 8 and riding freely in slots in said bar. Pivotally attached to the plate 8 at 74 near the lower end ot' the rack bar 17 is a lever 75, the free end of which is slotted and fastened to the vertically moving bar by a pivot pin 76. Also pivoted to the plate 8 adjacent the lever 75 is a bell crank lever 78 the upper end of Which has attached thereto a spring 79 the other end of said spring being attached to the plate and tends to normally hold said. bell crank lever in the position shown in Figure 2. The lower end of this bell crank lever carries thereon a roller S0 which rests against the top ot' the detent 60. Midway between the ends of the lever is a pin 82 which presses on the top of the lower arm of the bell crank lever 78 and will, when the lever 75 is depressed, force the lower arm ot bell crank lever 78 downward causing roller 80 to disengage the detent 60 from pinion 16. The parts just described are operated once for each revolution of the shaft and signal llag 4 and when operated reset the dial indicating extra charges, to initial position. Journaled in the trames 8 and 9 is a shaft on the inner end of which is fastened a pinion 91 which meshes with and is driven by the gear 37 carried on stud 35. Mounted on the rear end of this shaft, within a cut out portion in the back plate, is a gear 92 which meshes With and drives a gear forming part of a standard device 'tor recording the total eXtra charge transactions. Each time the pavvl 29 moves gear 37 said gear in turn moves pinion 91, shaft 9() and gear 92 and by progressive operations records in total the several amounts shown on the dial 12. In View of the fact that the mechanism for showing the total. eXtra charge transactions forms no part of the present invention, details of the same` have not been shown.

The operation of the device, assuming the signal dag to be in the position shown in dotted lines in Figure 1. in which position the taxirneter is inoperative` is as follo-ws:- The signal flag is turned to the position shown in full lines in Figure 1 rendering active the recording mechanisms of the tax'- imeter and permitting the extra` charge mechanisms to assume the position shown in Figures 2, 5 and 7. Presupposingl the eX- tra charges to be $1.20 and the dial 12 in the position shown in Figure that is, so that only 0 shows through'opening 14, the vehicle operator turns the handle causing cam rollerdl to ride on one offthe high por-4 tions of camf5 2 thereby movi rock arm 27, in turn pulling arm 28 and drawing pawl 29 backward one `tooth on gear Wheels 36l and 37. Immediately the C'am 52 is turned far enough, the cam roller under the influence of spring 56, Wil-l enter one of the cut away portions 52', moying rock arm 27 in the opposite direction toits first movement carrying with it arm 28 thereby causing pawl 29 to advance the gears 36 and 37 one tooth. The advancement of gear 36 Will drive pinion 38, shaft 19 and pinion 18, thereby actuating the rack bar 17 causing pinion 16 to advance the dial 12 until the numeral 2 shows through the opening 14. Each half revolution of the shaft 53 will repeat the operations above described causing the dial to advance one numeral until the desired eXtra charges are recorded, at the same time the total recording device, through gear 37 Will register the amount shown on the dial 12 in the manner hereinbefore described. When it is desired to restore the several parts to initial position the Hag 4 is turned completely around to the dotted position shown in Fig ure 1, this Will cause cam on shaft 65 to engage cam roller 71, and push the bar 72 downwardly thereby moving lever 75 and causing pin 82 thereon to engage and depress bell crank lever 78, in turn forcing the roller against the top of de-tent 60 and disengaging said detent from inion 16 permitting rack 17 to be returned) to initial position (Figure 3) by bell crank lever 23, under the influence of spring 25. rIl'he upward movement of the rack bar will reverse the movement of the pinion 16 and reset the dial 12 to the position shown in Figure 3. The rack and dial are limited in their movement by the stop pin 17' engaging the guide plate 20. At the same time cam 70 engages bar 72, cam 68 will engage cam roller 69 on 4bell crank lever 47 rocking said bell crank lever in a manner to cause its lower arm to engage the pin 46 on dog 41 and disengage said dog from gear 36. Rocking the bell crank lever 47 also forces its upper arm against the pin 49 on arm 28. thereby lifting said arm and freeing the pawl 29 from engagement with the gears 36 and 37. Thus it Will be seen that do 41 and detent 60 are simultaneously release to permit the rack bar 17 and dial 12 to return to initial position in which position the dial, rack and several operating parts remain until the flag is again turned to the position shown in full lines in Figures 1 and 2, when the operations above described can be repeated.

Of course it should be understood, that changes can be made in the construction and application of this device Without departing from the spirit of my invention.
